The Marine Air Ground Task Force Training Command, Marine Corps Air Ground Combat Center (Combat Center) is the premier service-level, live-fire and maneuver training base in the Marine Corps. Since 1952, Marines have relied on the Combat Center to prepare them for battle, with enough space to train as they must fight.
Because of the Combat Center's sheer size, 1,102 square miles (roughly the size of Rhode Island), the training conducted here cannot be replicated anywhere else in the world. The vast expanse of rugged Mojave Desert terrain is the perfect venue for the realistic, combined-arms training required to prepare Marines to successfully complete combat missions across the globe. More than 50,000 active-duty and Reserve Marines and sailors, and other U.S. and allied forces train at the Combat Center 350 days a year.
The Marine Corps' leading role as a modern expeditionary, rapid-response force requires Marines to be perpetually ready at a moment's notice. When Marines are called into action, they form what is known as a Marine Air-Ground Task Force (MAGTF), bringing together under one commander the ground, air and logistics elements needed to ensure mission success.
The Marine Corps' philosophy, "centralized planning, decentralized execution," requires that every Marine participating in a mission, regardless of rank, know his or her role and responsibilities, and be prepared to make split-second decisions to carry out those responsibilities in an arena where failure is never an option.
The only way to ensure mission success is consistent, realistic training that prepares Marines for the real-world challenges they may face in an ever-changing landscape of opponents, battlegrounds, objectives, technologies and cultures.
Quick Timeline of Milestones
1952: The Marine Corps formally establishes a training center at Twentynine Palms.
1957: The site is upgraded to Marine Corps Base status.
1976: Construction is completed on the Strategic Expeditionary Landing Field (SELF).
1979: The base officially becomes the Marine Corps Air Ground Combat Center (MCAGCC).
2000: Redesignated as the Marine Air Ground Task Force Training Command (MAGTFTC).
The World War II Era: Flight and Gliders (1940–1945)
Long before the rumble of tanks and the roar of fighter jets echoed through the desert, the area was known as Condor Field.
In 1941, as the United States prepared for World War II, the Army Air Forces recognized the desert's clear skies, dry air, and vast horizons as perfect for flight training. They established the Twentynine Palms Air Academy here in early 1942.
Over the next 15 months, the academy trained more than 1,600 glider pilots. These gliders were critical for stealth troop transport behind enemy lines. In 1944, the Navy took over the site, renaming it the Naval Auxiliary Air Station Twentynine Palms, but when the war ended in 1945, the airfield fell silent and its future was uncertain.
The Marines Arrive: A New Training Ground (1952–1957)
During the Korean War, the Marine Corps realized it urgently needed larger, more versatile live-fire training ranges. Camp Pendleton in San Diego was growing crowded, and commanders looked eastward to the wide-open spaces of the Mojave.
On August 20, 1952, the Marine Corps issued Post Order 343, officially establishing the Camp Detachment Marine Corps Training Center, Twentynine Palms.
A small band of pioneering Marines, led by Lt. Col. Frederick H. Scantling, arrived at the abandoned Condor Field to oversee construction. By December 1952, the 3rd Marine Division conducted the base's first large-scale, live-fire field exercise. This event showcased the desert's immense potential for realistic, unrestricted military training.
By February 1, 1957, the training center had grown dramatically and was officially designated as Marine Corps Base, Twentynine Palms.
The Evolution of Modern Combat Training (1976–1979)
In the late 1970s, the 26th Commandant of the Marine Corps, General Louis H. Wilson, recognized that modern warfare required a unified approach integrating infantry, artillery, aviation, and logistics. This concept became known as the Marine Air Ground Task Force (MAGTF).
To support this vision, major infrastructure upgrades were launched:
Strategic Expeditionary Landing Field (SELF): Completed in 1976, this state-of-the-art expeditionary airfield allowed military transport aircraft and fighter jets to land right in the heart of the training area.
A New Identity: With this brand-new air-ground capability, the base was renamed the Marine Corps Air Ground Combat Training Center in 1978. Only a few months later, on February 16, 1979, it received its iconic name: Marine Corps Air Ground Combat Center (MCAGCC).
The "Combined Arms Exercise" (CAX): This revolutionary program allowed live infantry, artillery, and close-air support to train simultaneously at a scale never before seen.
The base also created the Tactical Exercise Control Center, bringing in specialized instructors (known colloquially as "Coyotes") to control and critique the training. As base historian Col. Verle E. Ludwig put his thoughts, the Combat Center had become a permanent "combined-arms exercise college."
Into the 21st Century & Beyond (2000–Present)
On October 1, 2000, the command was designated as the Marine Air Ground Task Force Training Command (MAGTFTC), though the facility itself remains widely known as MCAGCC or The Combat Center.
In the post-9/11 era, the Combat Center became irreplaceable. It hosted Mojave Viper, a highly realistic pre-deployment training program that prepared tens of thousands of Marines for the unique environmental and urban challenges of operations in Iraq and Afghanistan.
Today, the Combat Center continues to evolve. It is currently being modernized to support Force Design training concepts, ensuring that the Marines of today and tomorrow are always prepared to protect our nation's freedom.
The Combat Center maintains a substantial and highly dynamic population to support its mission as the Marine Corps' premier live-fire combined arms training installation. The permanent on-base population is estimated to exceed 57,000 personnel. This demographic footprint is led by approximately 12,500 active-duty service members, who are supported by an estimated 24,000 military dependents residing both on and off the installation. Additionally, the base employs a civilian workforce of roughly 21,000 Department of Defense (DoD) civilians and contracted personnel who manage daily operations, logistics, and training support.
The base population fluctuates significantly throughout the fiscal year due to transient training forces. Approximately 50,000 active-duty and reserve Marines, sailors, and allied forces rotate through MCAGCC annually to participate in essential pre-deployment exercises, such as the Integrated Training Exercise (ITX).
